Mysterious decoding of green light on the Gulf of Thailand

A photo of Bangkok, Thailand from outer space is currently causing Twitter fever. The special thing is that the photo shows hundreds of brilliant blue lights off the Gulf of Thailand.

"Bangkok is a splendid city. But there is blue light outside the city? I wonder what it is ." , which is a description of a photo posted by Reid Wiseman on Twitter on August 18 just past.

In the picture, the city of Bangkok shimmered with lights and light emitted from stars and moonlight reflected on the surface of the Earth on the horizon. But in the lower right hand corner, the reader will see a lot of prominent blue-green light spots in the night of the Gulf of Thailand. Is that algae bioluminescent? Secret gamma ray laboratory? Or the underwater base of aliens?

The answer turned out to be very . normal.Those green light emitted from fishing boats use large power LEDs to attract ink and marine life to the surface. According to NASA's Earth Observatory article, " fishermen in South America and Southeast Asia light the ocean with high-powered lights to attract plankton and small fish that are their food. Ink squid will track their prey to swim to the water, where they will be caught by fishermen Squid fishing boats can carry hundreds of such lights.The light that each boat emits can reach 300kW ".

Seen from outer space, the light emitted from the "army" squid can rival the light of a big city. But what if it looked directly from the sea? Let's admire the photo shared by a blogger specializing in travel to have a more panoramic view of this "mystery" event.
